AT1320M Gamma Activity Monitor

AT1320M Gamma activity monitor is a fixed scintillation radiometric unit, designed to measure volume gamma-radiation activity of 51Cr, 99mTc, 111In, 123I, 125I, 131I and 201Tl radionuclides in liquid radioactive waste.  Measurement geometry - Marinelli beaker, 1.0 litre

Operating principle
 
AT1320M Gamma activity monitor operating principle is based on sample radionuclide gamma radiation detection by scintillation detector, instrument spectrum measuring and further matrix method processing with measuring of monitored radionuclide volume activity.
     
Radionuclide activity data is displayed on Information processing unit screen in real-time.
 
Setting up procedure and parameter check is performed with 133Ba check sample.
 

Application
 
  • Nuclear medicine
  • Radiopharmacy 
  • Radioecology
  • Radioactive waste control 
 
Features 
 
  • Spectrometric smart probe with built-in continuous automatic LED stabilisation of energy scale and parametric temperature stabilization
  • Memory function and automatic background subtraction for volumetric activity measurement
  • Recording and storing in memory up to 300 measured spectra
  • PC with dedicated software can be used instead of data processing unit to provide documentation function and for expanding of monitored radionuclides library
